Tearing down Disney’s Glow with the Show props

[Andy’s] boss recently returned from a trip to Disneyland with a set of light-up [Mickey Mouse] ears in tow. He said that during the event, every set of “Glow with the Show” ears in the crowd changed colors in sync with the performance. After he and some co-workers speculated on how this was pulled off, [Andy’s] boss gave him a new assignment – to find out how the darned things work!

[Andy] carefully disassembled the ears, sharing his findings and speculations with us. Inside, he found a small flexible circuit board powered by three AAA batteries. At the center of the device resides a TI MSP430G2553 which is tasked with controlling the RGB LEDs embedded in the ears.

In one ear, he spotted what he believes to be a Vishay TSMP6000 IR receiver. Vishay-branded or not, he verified that it does indeed pick up IR signals using his oscilloscope and a TV remote. In the other ear, he found a pair of small IR diodes, which he speculates are used to repeat the IR timing/sync signal received in the opposite side of the device.

The synchronization methods seem completely different than those found in the Xylobands we covered a while back, so we’re really intrigued to find out more about technology behind them.

Stick around to see a video of the light show in action, and since [Andy] says he’s willing to entertain any thoughts on how Disney makes their magic happen, be sure to sound off in the comments.
